Abstract
There is provided a cleaning blade for an electrophotographic apparatus having good cleaning performance both immediately after long-time shutdown under low temperature environment and during continuous use under low temperature environment even when spherical toner having a small diameter is used. A cleaning blade for an electrophotographic apparatus having an elastic blade member which is brought into contact with an image bearing member and frictionally slid to remove remaining toner, wherein the elastic blade member satisfies (1) to (4): (1) the stress-relaxation rate represented by the formula (a) at 10° C. is 25% or less;(2) the international rubber hardness (IRHD) is 65 or more and 80 or less; (3) the stress upon 100% stretching in a tensile test is 3.0 MPa or more and 5.0 MPa or less; and (4) the peak tan δ temperature in a dynamic viscoelastic test is −20° C. or more and 0° C. or less.
